more consistent over chrono (+-2 compared to +-5 with stock bolt)
FPS jumped up +5 over chrono (good paint to bore match and no tweaking of the regulator)
Quieter (almost as quiet as my DM)
Smoother (very slightly)

cons

consistent bolt stick (1st time was to much lube, 2nd time was bolt tip was coming off and causing the full auto syndrome) would also have bolt stick from first air up of the day.

what we did was put a light dab (1 drop) of super glue to the soft tip so it would not come off. The downside is that if you want to take it off you have to rip off the tip. good thing it comes with another one. i think ill give it one more try when i put it into my geo 2.1 when it comes in

it wouldn't be so bad if it was cheaper by $10-$15 but at $50 i could have bought a case of premium, a plate lunch and still have change for mcdonalds ice cream..

Just get your moneys back, buy a case of nice paint, and play with your stock Geo2s. Exalt shouldn't get to keep your guys money after putting out a product like that, especially since it hardly has any benefits either.
